Abstract
A process of manufacturing a member formed with a shaft-receiving opening in that a compact formed with a through hole and comprising a sinterable powder is subjected to liquid-phase sintering is improved in that a bushing, which is made of a material produced by fusion metallurgy and is dimensionally stable under the conditions under which the compact is to be sintered, is inserted into the through opening of the compact with a play which is smaller than the extent of the unrestrained radial shrinkage of the compact at its through opening during its liquid-phase sintering, and the compact is subjected to liquid-phase sintering after the bushing has thus been inserted.
